8 Claims.

This invention is for improvements in or relating to wrapping articles. Where herein and in the appended claims the term length or lengthwise is applied to the wrapping material or to the articles to be wrappedit refers to length considered in the direction of movement of the part referred to whilst the wrapping material is being folded into an open-ended tubular Wrapper.

According to one form of the present invention there is provided a method of wrapping articles which comprises bringing the articles into contact with wrapping material (e. g., a web from a reel or severed lengths) the length of the wrapping material in all cases being arranged to extend beyond the leading and rearends of the articles, moving the articles together with the wrapping material and during such movement forming the wrapping materialinto tubular form about the articles, the throughway of the tube Figure 1. being in the direction of movement, and if neces- Figure 4 is a sectional elevation on line 4 4, sary securing the seam (e. g., by adhesive), sever- Figure 1.

Figures 5 to 13 inclusive illustrates various stages `during the formation of a wrapper about an article, the arrows indicating the direction of movement of the article and wrapper during the folding of the wrapper about the article.

Figure 141s a side elevation showing a modiiied ing the wrapping material between successive articles in the case where there is not apreviously cut portion of wrapping material for each article, and closing (e. g., by folding or twisting) the open ends of the tubular wrappers. The articles may be placed at substantially equally spaced intervals along a length of continuous wrapping material, or the articles may be moved into engagement with wrapper blanks and disposed relatively thereto in a manner such that the blanks extend beyond the ends of the articles.

Further according to the invention there is provided a machine for wrapping articles comprising means to move an artitcle and wrapping material (e. g., a length of material greater than Ithe length of the article) into engagement with each other, means to move the article and wrapping material in a lengthwise direction, means to form the Wrapping material during such movement into an open ended tubular wrapper about Figure 1.

construction of a parto! the machine shown in i Like references refer to like parts throughout the speciiication and drawings.

Referring to Figures 1 to 13, the articles to be wrapped are enclosed in blanks of mapping material. Wrapper blanks 30 are severed by kniv 3| and 32 from a continuous web 33 of wrapping material fed from a reel, not shown. The blanks severed from the continuous web 33, are received between endless bands 34 and 35, which are rubber bands or composite bands the blank engaging surfaces of which are rubber or lave properties similar to that of rubber. 'I'he )ands 34 and 35 are arranged as shown in Figure l, from which it will be seen that the bands are arranged in two pairs which are spaced apart and engage with the wrapper blank at spaces adjacent the longitudinal edges thereof. 'I'he bands 34 and 35 carry the wrapper blank past an adhesive applying device which comprises a roller or disc 36, arranged to receive adhesive from a roller 31 rotating in an adhesive bath 33. 'I'he adhesive applying roller or disc 36 is arranged to apply a line of adhesive 39 as shown in Figure 5, the line of adhesive being adjacent one longitudinal edge of the wrapper blank 30 and extending along the whole length of the wrapper blank (see Figure 5).

vAfter the adhesive has been applied to the wrapper blank, the blank is carried by the bands 34 and 35 to a position at which it is moved in a horizontal path and is received by a conveyor which in the machine being described comprises an endless band 39 having a blank receiving surface similar to that of the bands 34 and 35 (i. e., a rubber or like surface) and which moves between the two pairs of bands 34 and 35. In the machine being described, the wrapping material is material such as that which is sold under the registered trade-mark Cellophane, and it is found that such material adheres to a rubber sur` face in a manner such that it is firmly gripped thereby and is not easily displaceable thereon.

Articles 40 to be wrapped are carried from any suitable source (not shown) by an endless band 4|, the articles being moved as a column, as shown in Figure l. The leading packet of the column is arrested by a stop 42, and is then engaged by a pusher piece 43 carried by an endless conveyor 44. The endless conveyor 44 comprises two chains, the sprockets for which are arranged as shown in Figure 3, and each pusher piece 43 is pivotally mounted on plates 45 secured to the chains. By reason of the arrangement of the pusher pieces relatively to the conveyor, the pusher pieces are at the beginning and end of their operative path moved through a vertical path and into and out of engagement with an article. The pusher pieces 43 are moved in timed relationship with the speed at which the wrapper blanks 30 are fed to the band 39 and are arranged to position an article upon a wrapper blank as shown in Figure 5, so that the wrapper blank extends lengthwise beyond the leading and rear ends of the article.

The conveyor 39 conveys the wrapper blank and article lengthwise between twisted bands 46 and 41, which fold the wrapper blank into a U-shape about the article, as shown in Figure 6. Whilst the wrapper blank is being folded by the bands 46 and 41, the article is still controled by means of the pusher piece 43, and this pusher piece continues to control the article until just before the article and wrapper blank are moved between folding elements 48 and 49, which fold the upstanding limbs of the U into engagement with each other, as shown in Figure 8, to form a seam. Figure 7 illustrates the wrapper as though one limb were completely folded into engagement with 'the article before the folding operations are comrspiral folding elements of the usual known type and operating to fold the upstanding limbs of the wrapping material downwardly about the support 51, which support facilitates the downwar folding of the upstanding portions and also has a further function which is referred to below. The seam formed asshown in Figure 8 is secured by means of the line of adhesive 39.

After passing between the twisted bands 46 and 41,` the articles and wrappers are carried by the band 39 between two further endless bands 5|! and 5| which move at the same speed as that at which the band 39 is moving, and which are arranged to grip the sides of the partly wrapped articles. The tension of the belts 50 and 5| may be.adjusted by means of jockey rollers 52 and 53, the spindles of which' are movable in slots 54 and 55. When the bands 56 and 5| have been adiusted, the spindles of the rollers 52 and 53 are clamped in position.

When the wrapper has been folded so that it forms an open ended tube about the article, the ends of the tubular wrapper extend beyond the leading and rear ends of the article as shown in Figure 8, and the partly wrapped articles are carried beneath a heating element 56, which presses upon the seam of each wrapper and dries the adhesive by means of which the seam is secured. It will be seen that those portions of the tube which extend beyond the ends of the article are unsupported, and in order to provide means whereby the whole of the seam of the tubular wrapper may be dried and secured, a thin plate 51 is provided. 'Ihe plate 51 rests on the tops of the articles being wrapped before the upstanding limbs of the U are folded into engagement with each other and extends along the whole of the length of the heating element 56, and is supported by the successive articles being moved by the band 39 so that the heating element presses the seams of the successive wrappers against the bar 51. By this means those portions of the wrappers which extend beyond the leading and rear ends of the articles are dried and secured.

The bands 39, 50 and 5| deliver the partly wrapped articles on to a stationary plate 58, and rotatable gripping members 59 and 60 are arranged to grip the articles as they leave the bands and move the partly wrapped articles against stops 6| and 62. The stops 6| and 62 are pivoted at 63 and 64 respectively, and are connected with links 65 and 66 which are in turn connected with one arm'of the bell crank lever 61. The other arm of the bell crank lever carries the cam follower 68 which engages with a cam 69. 'I'he ends of the stop 6I and 62 which engage with the partly wrapped articles are provided with lips 10 and 1I (see Figure 3), and these lips engage with the end of the article to eifect the location thereof and also serve to partly fold the open end of the tubular wrapper. As the article is brought into position to be arrested by the stops 6| and 62, the stops are turned about their pivots 63 and 64 until they assume the position shown in Figure 3. and locate the partly wrapped article. 'Ihe links Il and 88 are slotted at those ends which engage with the stops il and 82, and the ends of the stops 8| and 62 are provided with pins which engage with the slots in the links 85 and 8B. The purpose of the slots in the links 65 and 68 is to provide a means of adjustment whereby the apparatus may be arranged to deal with articles of varying sizes. When the apparatus is set for a particular size of article to be wrapped, the stops 6| and 82 are secured relatively to the links 65 and 88.

When the partly wrapped article has been positioned by the stops 8| and 62,"a plunger 12 (see Figure 4) operated by a cam 13 through the medium of a bell crank lever 1I moves the article transversely of the direction of movement in which it was moved whilst the wrapper blank 38 was folded into tubular form about the' article, and the partly Wrapped article is inserted by the plunger 12 into a magazine constituted by a liixed plate 15 and a resilient topmember in the form of a brush 16. As each partly wrapped article is ejected by the plunger 12, the leading article in the magazine is moved into the path of one of the pusher pieces 11 carried by an endless conveyor 18, and the pusher piece conveys the partly Wrapped article through 90 and places it upon the surface of the' bed 19 of the machine. Whilst the article is being conveyed from the plate 15 and deposited on the bed 18 it is controlled by means of a guide 88, which is shown in the drawings as a brush.

When the steps 8| and 62 are moved out of engagement With the article, after positioning it to be engaged by the plunger 12, the partly folded end of the Wrapper tends, `due to the resiliency of the wrapping material, to assume substantially the tubular shape which the partly folded wrapper had before being engaged by the stops 6| and 82. As the pusher 11 moves the partly Wrapped article along the bed 19, the open ends of the tubular wrapper are engaged rst by stationary folders 8| and 82 which form the narrow end folds 83 (see Figure l0) at the ends of the Wrapper, and then by rotating elements 84 and 85, which form the narrow ends 8B (see Figure 10) The folding of the narrow end folds 83 and 86 causes broad end iiapsf81 and 88 to be formed, and in order thorughly to crease the small triangular folds 89 which occur on `both the broad aps 81 and 88, the broad flaps 81 and 88 are passed between pressing rollers 98, 9|, 92 and 93 (see Figure 4). The broad ilaps 81 and 88 are folded upwardly as shown in Figure 11 by means of fixed folders 9| and 95, and `the partly Wrapped articles as shown in Figure 11 are moved past rotatable adhesive applying wheels 8B and 81, which receive adhesive from the discs 98 and 99, rotating in adhesive baths |88 and IM. The wheels 98 and 91 apply lines |82 of adhesive to the upstanding aps 81, after which the pusher piece conveys the partly wrapped article between folders |03, which fold the upstanding flaps 81 downwardly into engagement with the flaps 88.

The line |82 of adhesive which is applied to the ap 81 does not extend to the edge of the ilap 81, so that when the flap 81 is caused to engage the flap 88, the extreme end portion of the flap 81 is not secured to the ilap 88. 'The unsecured end portion of the flap 81 provides a means by which the Wrapper may be gripped when it is desired to open the wrapper, and in order to enable the free portion more readily to be gripped,

folding element |84 (see Figure 4) engages with the free end portion of the ilap 81. and folds the free end portion upwardly against the outer surface of the broad end flap 81. If desired, a printing or other ink applying device may be provided to apply colouring matter to the free end portion of the aps 81 to make the free portion distinctive. The wrapped articles are4 thereafter delivered by the pusher pieces 11 to any suitable collating device, and the adhesive between the broad end iiaps 81 and 88 may be dried by any of the well known heating elements, which may be caused to engage with the broad end iiaps either before or after their insertion into the collating magazine.

It will be appreciated that instead of the wrapper blanks being of a length such that the tubular wrappers extend beyond the leading and rear ends of the articles being wrapped, they may be of a length equal to or shorter than the length of the article. In cases such as this the mechanism for closing the ends of the tubular wrappers will not be needed.

Referring to the modified construction shown in Figures 14 to 24,*Vthe wrapping material, instead of being cut into Wrapper blanks, as was the case in the construction above described, is fed as a continuous web 33 from a reel 33a. The continuous web 33 is carried by an endless band through folding mechanism described below. which folds the wrapping material into a continuous tubular Wrapper about the articles to b wrapped.

The articles to be Wrapped are stacked in a magazine |86, the magazine being inclined in the direction of movement of the continuous web of wrapping material, and the lowermost article in the magazine is supported as shown in Figure 16 by an inclined plate |81.

The article being supported by the plate |81 is moved into engagement with the travelling web of wrapping material by means of a plunger |08 which moves the article out of the magazine and the inclined plate |01 is shaped so that the article assumes an upright position on the continuous web of wrapping material, as shown in Figure 17. It will be seen that by this means the article is given a component of movement in the direction of movement of the web 33 of wrapping material before it is fully supported thereby, and the movement of the'plunger is such that when the article is fully deposited upon the web 33, it is moving in the same direction as and at the same speed as the web 33. The web 33 carries the article between guides |09 and H0, and the web of wrapping material is folded into a U-shape about the articles by means of a series of pairs of slotted guides H2, H3, which engage with the longitudinal edges of the web 33. Each successive pair of guides ||2, ||3 is arranged more closely together than the preceding pair in order to form the wrapping material gradually into a U shape about the articles carried by the wrapping material.

The wrapping material is moved past an adhesive applying wheel H4, which receives adhesive from a disc ||5 rotating in an adhesive bath IIS, and the wheel lil applies a line of adhesive along the whole length of the web of material and adjacent one longitudinal edge thereof as seen clearly in Figure 18. The band |85 and wrapping material 33 then carries the articles past the apparatus which is arranged to locate each successive article upon the wrapping material relatively to cutting mechanism, which will be described below, and which is arranged to Gli sever the continuous tubular wrapper at points substantially midway between successive articles contained therein. The locating device is indicated generally in Figure 14 by the reference H1, and is shown more clearly in Figure 19. A rotatable disc ||8 is driven in timed relationship with the cut-olf mechanism, and carries four pivoted fingers H9. Each finger |I9 is provided with a cam follower |20, which engages with a cam |2| fixed relatively to the disc H8. The fingers ||9 are arranged to engage with the rear end of each article conveyed by the band and web 33, and place the same in the desired position upon the wrapping material. Springs |22 are provided to control the fingers H9.

When the articles have been located upon the wrapping material 33, the band |05 together with the wrapping material 33 and the articles thereon are moved between folding elements |23 and |24 which fold the upstanding edges of the U formed by the wrapping material into engagement with the upper surfaces of the articles and into engagement with each other, so that the overlapping longitudinal edgcs of the wrapping material form the seam which is secured by the line of adhesive above referred to. The folders |23 and |24 fold the wrapping material about a thin plate 51, which is provided for the purpose described above with reference to the construction shown in Figures 1 to 4 of the drawings. The tubular wrapper and the articles contained therein are thereafter moved beneath a heating element 56. After passing the heating element 56 which dries the adhesive securing the seam of the wrapper, the tubular wrapper, together with the articles, is moved to cutting mechanism indicated generally in Figure 14 by the reference |25, which severs the continuous tube substantially midway between two successive articles, as shown diagrammatically in Figure 24. 'Ihe cutting mechanism comprises a ledger plate |26 having an aperture |21 through which the tubular wrapper and articles pass, the ledger plate |26 being carried on a bracket |28, which is mounted on guides |29, |30, along which the bracket is arranged to slide. A link |3| is connected to the bracket |28, and the free end of the link is connected with a crank |32. 'Ihe crank causes the ledger plate to move in the direction of movement of the continuous tubular wrapper, during the cutting operation, and at the same speed as the speed at which the continuous tubular wrapper is moving, so that the knife |33 co-operates with the ledger plate during the severing of the tubular wrapper.

The knife |33 is shown in the drawings as a circular disc which is rotatably mounted on an arm |34, the arm I 34 being pivoted about a spindle |35. The knife |33 is rotated about its axis by a pulley |36, which is connected by a belt |31 to a driving pulley |38, slidably mounted on the spindle |35. The pulley |33 is restrained against rotary movement relatively to the spindle |35 by keys |39. and the boss of the pulley |38 is slotted to accommodate the keys |39, and also extends through the arm |34, as can be seen in Figure 22.

During the cutting operation, the knife |33 has a complex movement, being moved transversely of the direction of movement of the continuous tubular wrapper in order to sever the wrapper, and also being given a component of movement in the direction of movement of the tubular wrapper, the knife being moved in the same direction as and at the same speed as that at which the continuous wrapper tube is moving during the severing of the tube. The movements imparted to the knife during the cutting operation are effected as follows:

The movement imparted to the knife in the direction of movement of the wrapper tube is provided by means of a crank |40 to which is connected a link |4| secured to the arm |34. The crank causes the arm |34 and the driving pulleys for rotating the knife to reciprocate axially of the spindle |35. In order to move the knife transversely of the direction of movement of the continuous wrapper, a cam |42 engages the cam follower |43 connected to one arm of a lever |44, which is pivoted at |45. The other arm of the lever is provided with a slotted guide |46 (see Figure 23) and a sliding block |41, connected with the arm |34, is located in this guide and causes the arm |34 to follow the movements of the lever |44. As the lever |44 is rocked about its pivot |45, the arm |34 is in turn rocked about the spindle |35, the arm |34 being mountedv as shown in Figure 22 so as to be free to oscillate on the boss of the pulley |38, and this movement causes the knife |33 to be moved transversely of the direction of movement of the tubular wrapper.

When the continuous tubular wrapper is being severed by the knife I 33, it is found that there is a tendency for the continuous wrapper to tear, and also for the articles to become displaced slightly relatively one to the other. To reduce this tendency, there is provided on each side of the knife |33 a pair of rotatable rollers |40 an-d |49, the pair of rollers |48 being arranged to engage with the article on one side of the knife |33, whilst the pair of rollers |49 is arranged to engage with the article on the other side of the knife |33 during the cutting operation which severs the tubular wrapper. The rollers |40 and |49 are moved with a slightly greater surface speed than that at which the continuous wrapper and articles are being moved, so that the tubular Wrapper is pulled taut. It will be seen that the rollers |48 and |49 are arranged to grip the articles both during and after the severing operation, and that by this means the tubular wrapper is tautened during the cutting operation, and the articles Within the tubular wrapper are controlled both before and after the cutting operation has been completed.

After the cutting operation has been completed, the severed length of tubular wrapper, together with the article contained therein, is gripped between a pair of co-operating belts |50 and |5|, which move the tubular wrapper and article at a speed which is greater than the speed at which the continuous tubular wrapper is moving, and by this means the severed lengths of wrapping material and the articles contained therein are spaced apart in the direction of movement thereof. The bands |50 and 5| then deliver the partly wrapped articles to stops such as the stops 6| and 62, described above, and the tubular wrappers are thereafter closed in the manner above described with reference to Figures 1 to4.

The construction described with reference to Figures 1 to 4, in which the tubular Wrappers are formed from wrapper blanks is preferred to the construction shown in Figures 14 to 24, because in the construct-ion shown in Figures 14 to 24, it is necessary when starting the machine to feed the continuous web of wrapping material through the machine before starting to operate the machine, and it is found that this is a somewhat cumbersome proceeding, due to the width of the material used and the length of the material which has to be fed through the machine before starting up the machine. With the machine shown in Figures 1 to 4, the machine when started up is entirely automatic, and the diillculty experienced with the machine described with reference to Figures 14 to 24 is avoided.-

By means of machines constructed in accordance with the present invention it is possible to wrap articles in tubular wrappers at a very high speed. that is, speeds of between 500 and 1,000 per minute, and it is found that in some instances it is not possible to provide mechanism to close the open ends of the wrappers at this high speed. In such cases, instead of the open ended tubular wrappers containingV articles being moved into one set of closing mechanism, there may be provided two sets of closing mechanism arranged for example side by side, and the open ended tubular wrappers, together with their articles, may be moved alternately to each of the closing mechanisms. In this way it will be seen that the closing mechanism need only operate at half the speed at which the mechanism for forming the tubular wrappers about the articles operates. l

Such an arrangement is shown in Figures 25 and 26; wherein certain of the mechanisms previously described have been omitted to promote clarity of illustration. The plunger 12 (Figure 1) is replaced by a reciprocating ejector |60 which comprises a fiat vertical plate having a downwardly extending arm to which is secured a slide |6i. The latter is slidably mounted in a guide i6?, and is provided with a pin |63 which slidably engages a slotted lever |64. The latter is pivoted to a suitable portion. of the machine frame, as at |65, and carries a cam follower |66, for engagement with a cam |61, which latter is substituted for the cam I3 (Figure 4). A spring |68 maintains the cam follower |66 constantly in engagement with the cam |61'. It will be obvious that the ejector |60 is thus reciprocat'ed laterally, and is adapted to move a wrapped article to one side and then, upon its return, to move the succeeding wrapped article to the right, and so on.

Ihe closing mechanism of Figure 4 is duplicated on either side of the ejector mechanism, as indicated in Figures 25 and 26, each closing mechanism being adapted to receive alternate Wrapped articles from the advancing line of such articles, and to complete the closing operations as previously described.
